Fluid & Flight Mechanics Lab

The laboratory is equipped with a number of equipments to study the fundamentals and applied aspects of fluid mechanics. The setups are used for calibration and measuring the rate of flow by using venturi meter, orifice meter, notches, water meter, rotameter etc. Determination of losses in pipes are carried out by major and minor loss apparatus.


Pipe Friction Apparatus               

Darcy’s as well as Chezy’s coefficient of friction for different pipes can be found out in pipe friction apparatus

ventu meter


Venturimeter is a device used for measuring the rate of flow of a fluid flowing through a pipe.

It consists of three parts:

  • A short converging part
  • Throat
  • Diverging part

orifice meter

Orifice meter

Orifice meter: It is a device used for measuring the rate of flow of a fluid flowing through a pipe.

  • It is a cheaper device as compared to venturimeter. This also work on the same principle as that of venturimeter.
  • It consists of flat circular plate which has a circular hole, in concentric with the pipe. This is called orifice.
  • The diameter of orifice is generally 0.5 times the diameter of the pipe (D), although it may vary from 0.4 to 0.8 times the pipe diameter.

triangular notch

Triangular Notch

A notch is an opening in the side of a measuring tank or reservoir extending above the free surface. A v notch is used to measure the rate of flow in an open channel. The v notch is very good for measuring a low flow rate of open channel flow. The head over the v notch is measured and correlated with flow rate through the open channel. A v notch equation will give the open channel flow rate.

Metacentric Height Apparatus

We have a metacentric height setup in order to determine the metacentric height of a flat bottomed vessel in two parts:

PART (1) : For unloaded and for loaded pontoon.

PART (2) : When changing the center of gravity of the pontoon.
